good idea,, i too have beem thinking about what type of nutes i am going to use in my next grow,, mostly i want to use the trench method again, i was thinking about a fruit n flower trench on the back row, and a tomato fert in the front trench,
I also did a trench with some all purpose natural fert. I made some nice soil with Happy Frog, Green Tree Ultimate, guano, bone meal, perlite, and some lime. I put GroKashi on top of that, and once it did it’s thing I put a nice layer of lobster compost. I also dropped in an air stone under the whole thing. This will be my first real test with this method.

is the top of your SIP able to vent then?,, every grow i have done has been plastic covered, does moisture reach all the way to your top layer of soil with your method?

I use the cloth type covers that came with them. So, yea, it’s covered and it’s a little moist on the top, but not overly wet or anything. Right now I have one Bag Of Oranges in one sip and 2 Space Monkeys each in the other 2.

yup,, all of the plastic covers i have are used up now,, i dont plan on buying more from earthbox,, i was thinking of just laying plastic black trash bags over the top of the soil, i like how it keeps bugs from going back and forth into our out of the dirt ,,
yup sounds perfect on your soil moisture,, they should be just slightly wet at the top layer, ,, wet is almost too strong a word,, but you get the idea,, i like the burlap cloth type things,, i think i have one somehwere that came with the growbox, but i think they sewed some kinda nutes into the cover so i never used it

So, I had the two Purple Uni/Pure OG plants in one sip. It grows really stretchy and was trained under a screen. I ended up with 4 OZs dry:

I thought that was pretty awesome. The photo does not do it justice. IRL it's very purple and SO sticky.
Here is a Bag Of Oranges just about ready- 2 plants in one sip:

One of the most common replies here on RIU has to be

'Lift your pot before you water' check that weight..?

cause if you don't, you are just pouring more water into that soil blowing out even more air

and its this air that them root hairs need

fuck Rob now I'm rolling ...lol

some serious magic shit happens with roots

1: the plants sweats out some ouzzie slime to the rootlets

2: fungi spores in the soil helps it out in exchange for nutes

3: the ouzzie melts and sucks up nutes in the soil

4: the plant sends them nutes upstairs to return later to store in the roots as carbohydrates

air during this growing operation is just as important as water

its important that you let the plant decide on weather it wants/needs water or air at any given time

see this weed thing as a pet rather than as a machine, will give you ample dividends each time

good luck thanks for the Rant/...lol
Just reading through some of the old stuff, and this post made me wonder if the old "flood drain" I used to run really was the best for this , having the roots exposed to oxygen all day long except for those 2 or 3 flood session s that lasted a few minutes

Google Kratky I'm using that method now now pumps either

good luck

Hey Rob what parts do I need to do this , I might drill my earth box and run it?
You are in luck, while cleaning and organizing for the upcoming grow, I came across some leftovers from my last builds. I have three rubber grommets and three "barbed elbows" -- you can have them -- all you'll need is some 1/2 tubing. :)

I am really caught up on what i want to do for a growing container this time around, i have the earthbox and the grow box, i sorrta want more soil in the sips, so i am looking at 10 gallon storage tubs, and i could make 2 of them fit in the grow cab, stacked inside eatch other i think they would be about as tall as the earthbox, but hold more soil , at least more soil for each plant, , but i dont know that i need more dirt?,, i go round and round , seeing the Kratky method of hydro really interests me like Hempy bucket did,, but with Kratky that is no over flow, removing the mess that i didnt like with hempy, but it would have me back to mixing nutes and phing water,, ,, its kinda too late for this grow since i have purchased all the items to make the super soil , i need to get over to home depot, and measure some containers,, then if i build new sips, i need to get some net pots and guess at wick size,,

I personally despise Kratky. No circulation or changing of solution just makes no sense from a toxicity / nutrition perspective.
You can search youtube and there are many grows on many species of plants testing Kratky against an aerated system and in all of them the aerated system beats the pants of Kratky :peace:

Wow, that kind of made my head spin! hahaha I guess it depends on what brand/kind of bin you are using, I found that some kinds when they stacked inside each other didn't leave much room for the res. For instance an 18g in an 18g would give you 18 gallons of soil, but only about 1/4 (?) of that volume in water. That's why I fit a 14g into an 18g, I think that left me with 10g of water in the res. Those were heavy beasts to remove from the tent at the end of the grow! When I got down to 3g bins, I just stacked one on top of the other for a 3 over 3, which worked well for short (3-4 week) veg times.

My last SIP was 5 gallons of soil in a fabric pot over a 10g bin/res. That worked pretty well, but I'd like to up it to 7 or even 10 gallons of soil if I could to support a longer veg time. I will say that using the Rubbermaid's lid to hold the 5 gallon pot required that I build a structure out of PVC to support the weight of the wet soil, otherwise the lid sagged.

You mentioned having 10 gallons of soil, how big do you want the res to be?

I really appreciate the first hand knowledge , thank you for your feedback, saves me allot of time and headache, I am really enjoying your lettuce grow this time around, for a while I got all wrapped up in trying to decide if I wanted to trade in my cobs for a quantum board,, I would gladly try a bulb set up , I hear so much about cmh

Haha ya that was allot to digest, I dug out some old hard drives so I could see some older grows , and my normal veg time from clone is usually 3 weeks , 4 or more only if I do a partial mainline, and I am considering doing that , I could also see I was way over topping in my older grows just resulting in lots of tiny branches all over the place, , did anyone ever figure out the optimum soil amount for a water only grow to Last , 3 months or so total grow time ,
